Crowcon Detective Plus Transportable Area Monitor – Diffusion

Crowcon Detective Plus Transportable Area Monitor – Diffusion
The Detective+ is a temporary and transportable area monitor for use in various industries such as oil and gas.  The area monitor can be used on its own or linked together with the Detective Net (purchase separately) to create a wireless fence. 
The configurations above are diffusion and include sensors for LEL CH4, H2S and CO detection and O2 depletion/enrichment. You can choose from a standard battery or an extended battery.  The Detective Plus+ has a clear display for easy viewing of gas hazards.
